To all whom t may 'cof/warn:

Be it known that we, FnEDEIuoKY Gan-SERT and HERMAN GANsER'r, Jr.,'bothf o-t Syracuse, in the Acounty ofL Onondaga, in the State of' New York, have inventednew and useful Improvements in Methods of Forming and Alining' Type on theType-Barsgo TypeWriting-Machines, of which the following, taken in connection with'thev accompanying drawings,'is a full', clear, and exact description. y j

' This invention relates to a method of i forming and al'iningtype on the type bars of typewriting machines having' p'ivoted t pe bars which are usually` assembled in c ose, compactv relation in such manner as to cause their type toxassumersubstantially thel same printing position whenu the bars are operated. e j

In many machines of this character, eachA type bar carries two or more type or printing characters, which necessitates a very'. carefulY adjustment, commonly kno-wn as alining7T of the type, in order that both` characters may print` squarely-y upon the work in'eit'her position of adjustment of the platen'or segment and atV substantially the same printing point, all of which requires the employment of highly skilled and expensive labor and therefore, adds materially tothe cost of the machine. l j In many instances the type are attached to the type' bars byg-'me-ans ofsolder or some,v

equivalent attaching' means'whi'ch will' enable the type to be more easilyadjusted or alined, after the bars have been permanently` assembled in the machine,`resulting in more or less unreliability of securement' and' consequent displacement of the type, aftery a short period of use.

The main object of my present invention is to avoid the laborious and expensive op` erations of adjusting lor alining the type,

` andi squarely upon the work in either position otadju'stment of the platen or segment. Another Objectis to provide mea-ns whereby 'an entire set of type for the machine may be` simultaneously cast upon their respective bars'l in position for proper alinement, when the bars' are' assembled in the machine without anyfui'fther adjustment. -v

'- Other-objects'. and uses will bexbrought out in the `follou'r-ing description.A i

In-the drawings, Figure 1 'is a top plan,

partly 1n section and somewhat diagrammat1c',fo:t an apparatus by which the type may-be slmultaneouslycast upon a plurality of barsforming a part of the completeset Jfor a typewriting machine, although,for purposes of illustration, those shown may be rewarded' asa complete set.

Fig. '2 is a side elevation, partly in section', of the apparatus shown in Fig. l;V v

Fig. 3 is an. enlarged transverse sectional vlew` of a portion of the same apparatus, taken in the plane of line-A, Fig. 2.

Asrillustrated, the apparatus for casting the type, as -1'-, upon thetfype bars, as f2-1 comprises lower and upper mold sections -8-and 4l-1, meeting in the plane of linexB-B, Fig. '-22- and adapted to be clamped together. andreleased by suitable'bolts `In many of the usethetype bars' are pivoted near one end in the are of a circle, having its aXis passing approximately' vthrough' the printing point,l

so that when operated' from their normal positions of rest they will produce the desired vimpression upon the work at that point, the type being mounted upon the opposite vends'of the'bars to swing to and from the normal position of rest, which may also be' inl the arcy of a circle, preferably concentric'with the arc in which-the pivots are located and a distance therefrom corresponding approximately to the length of the bars, or substantially equal to the distance from the printing point, as to the pivots. This printing point amay be on the front face of the platen of a visible-writing machine`and the apparatus shown for casting the type upon the bars makesfuse of the segment -6- of. the typewriting machine secured by screws or equivalent fastening devices -7- to one of the mold sections, as -3-, said segment being disposed in a substantially horizontal plane about an axis machines now in common rot passing vertically through the printing point and having a series of slots 8- vradial to said axis and in uniformly spaced relation for receiving the adjacent ends of a corresponding number of the type Y bars 2 to be used 1n the machine with that particular segment. are provided with registering pivot holes through which a wire or other fastening device -9- may be passed to lock the bars to the segment during the process of casting the typewon the opposite ends thereof.

These bars fit snugly in their respective slots -8- and extend radially therefrom with their type receiving ends securely held in a corresponding number of similar radial slots -10- in a hardened section 11- of one of the molds, as 4-, the end walli of each lslot. -l0 forming an abutment l2- for the adjacent end of the corresponding bar -2 to additionally hold the bar against endwise movement.

The mold section -3- is also provided with a hardened section -11- directly opposite the section -llwhich, together with section .11-, are provided with communicating' recesses --137- and 14- in their meeting faces to form a series of relatively ishort and also relatively shallow chambers l5- registering with the adjacent portions of their. respective type bars -2- to receive the molten type metal, which is to be cast therein, around and upon the lower edges of said bars.

'That is, thetype receiving ends of the bars extend through the upper portions of the recesses 14- a'short distance from the lower wall of the recess --13-, each chamber -15- extending upwardly atl the side of the corresponding bar a short distance above the lower edge thereof and really forms an enlargement of the corresponding slot -10, which -otherwise is of substantially the same width als the adjacent bar 2- to coniine the molten metal to the chamber -15.

' Each of these chambers -15- is connected by a passage 1G- to a sorue l7- to which the molten metal is delivered under pressure for simultaneously filling all of the chambers -15- and thereby casting the type directly upon the adjacent portions of all the bars -2.

If desired, the type receiving end of the4 bar -'2- may be provided with one or more relatively small holes -l8 through which the molten type metal may How to establish an integral tie between the portions of the opposite sides of the bar, andv also to increase the permanency of connection between the type and bar.

The type receiving end of each bar is pro- These type barsU l vided with a rearward projection -19-, which is commonly employed in bars of this character to register with a guide slot (not shown) in the machine justbelow the printing point to hold the'type against'the'lateral 'vibration when printing.

Vhen the bars are assembled inthe mold, the lower edges of these projections-19 are caused to restlupon suitable pins 20- in the section -l1-, and also to close the intervening space at the rear end of the chamber -13- so as to confine the molten metal in said chamber. Y

. The upper edges of the ktypereceiving ends of the bars --2-, Vwh-en assembled in the mold, are engaged by pins 2lwhich are movable in the upper 'section ,-4 and are held ink operative position by spring fingers 29rto further prevent displacement of the bar, while'the type are being y cast thereon. s

Although we have not attempted to shofw the exact relation or angle of the chambers l5- relatively to their respective guide slots -8- and -10, it is, of course, understood that thel angles of the type relatively to their respective bars vary according to their position relatively to the printing point, and, therefore, each chamber l5- and especially the portion 13 thereof, will be made at a corresponding angle or in proper relation to its guide slo-ts -8- `and -10 in the mold. j

In other words, each type chamber *15- preferably bears the same relation to its Y corresponding guide slots -8 and lO that the type bears to the bar when assembled in the machine for actual use, so that, when the bars with thetype cast thereon are assembled in the machine upon their respective bearings, no further adjustment of the type will be necessary thereby avoiding the laborious and expensive work' of alining after the assembly.

What we claim is: o y

The herein described method of forming and alining type on the type bars of typewriting machines, consisting in supporting the type receiving portions of the several bars in fixed spaced relation within a suitable type-mold and then casting the type on the bar in a position to cause them to be properly alined for printing, whenV the bars with the type thereon are assembled in the machine. f

In witness whereof we have hereunto set our hands this 18th day oaf October 1920.
